High-Power Solid-State Switches Archives - Eagle Harbor Technologies

EHT developed a power supply capable of switching 40 kA at 100 kHz PWM for driving an inductive load (electromagnet coils). The supply consisted of sixteen IPM-16PPs operating in parallel at 2.5 kA per module for 10 ms. The figure below shows the collector-emitter voltage of the IGBT (Ch2) and the current in the load…
